Regression from 3.1.3,adding Regression keyword. RCA of this issue is same of BZ 1406723. Upstream patch : http://review.gluster.org/#/c/16298/ A new upstream patch https://review.gluster.org/#/c/16821/ is posted with a different alternative. 3.1.3 : 724 files/sec 3.8.4-17 : 549 files/sec regression : ~24% There is still a 24% regression. Failing QA and moving it back to Assigned.

Number of network operations is exactly same as 3.1.3 but the avg latencies increased in 3.2.0 Based on the testing I did, it seems to be because of l[g/s]etxattr for trusted.ec.dirty. I just provided a build to Ambarish to confirm if that brings the number closer. upstream patch : https://review.gluster.org/16865 bug added to erratum RHSA-2016:24866 moving bz to ON_QA 3.1.3 : 724 files/sec 3.8.4-18 : 694 files/sec Within the regression threshold on 3.8.4-18,Verified.

Just want to know what could be the reason for this, if you don't mind could you attach strace/profile info of these runs, so that I can find what is the reason for this difference.
